: On January 2, 2004, the Allen Flour Company purchased a new machine at a cost of $82,000. Installation costs for the machine were $3,000. The machine was expected to have a useful life of 10 years, with a salvage value of $3,000. The company uses straight-line depreciation for financial reporting. On January 3, 2007, the machine broke down and an extraordinary repair had to be made to the machine at a cost of $8,000. The repair extended the machine's life to 13 years but left the salvage value unchanged. On January 2, 2010, an improvement was made to the machine in the amount of $5,000 that increased the machine's productivity and increased the salvage value (to $6,000) but did not affect the remaining useful life.
